SPECIFICATION forming part of Letters Patent No. 317,149, dated May Application filed July 7, 1884. (No model.)

My invention relates to machines for cutting i out the leather blanks Vand cementing a sufcient number of such blanks together to form the heel of a boot or shoe; and it consists in improved devices for cutting out thel heelblanks and for applying paste or-cement to the same, and also in the combination of cutting and paste-applying devices and intermittently-revolving carriers, with means for 'discharging the heel-blanks from the receiving-openings of one of the revolving carriers into the corresponding chamberof the opposite carrier, and for compressing the accumulated contents of such chamber, and. means for discharging the heels so formed and compressed from the chamber of the carrier, and also in certain improved mechanical devices adapted vfor the successful operation of the various parts of the machine.

: Figure 1 represents a front elevation of the machine. Fig. 2 is an elevation of the lefthand side of the machine. Fig. 3 is a rear elevation of the same. Fig. 4 is a detail section showing the mechanismof the revolving oarriers and the heel-blanl cutters, the crossbarred plunger at one of the chambers of the delivering carrier-wheel being broken away to more plainly show the cross-grooves in which it is made to operate. Figs. 5 and 6 are detail views of the sliding head for operatingthe cutting-plunger and the paste-applying forcer. Fig. 7 is an end elevation of the clampingp iece which serves to secure the cutting-plunger tothe adjustable shoe of the sliding head. Figs. 8 and 9 are detail views of the clutch mechanism for stopping and starting the machine. Figs. 10, 111, 12, and 13 are detail views of the cutting-plunger, the pastingforcer, `and the inwardlyprojecting guideplates of the chambered wheel adapted to receive the blanks for the smaller portion of the heel- Figs. 14, 15, and 16 are detail views of the mechanism adapted to force the accumulated smaller blanks from the receiving-openings of one of the revolving carriers into the receiving-chamber of the opposite carrier.

Figs; 17 and 18 are detail views of the barred plunger adapted for delivering the completed heel from the chamber in which it is formed. Fig. 19 shows an end-elevation of the adjustable shoe which serves to hold the cuttingplunger. Fig. 20 represents a horizontal section of the lower end of the sliding head, taken in the line x x of Fig. 19. Fig. 21 represents avertical section of the sliding head and shoe, taken in the line y y of Fig. 20. Fig. 22 represents a horizontal section` of the holdingshoe, taken n the line z z of Fig. 21.

In' the accompanying drawings, A represents the supporting-frame of the machine; B, the table, in which the heel-blank cutters C C are securely held by means of the cutterholders D 1)', Vwhich are secured to the table B by means of the screws a a, the heads of which are out away at one side of the screw, in order that the cutter-holder may be released from the table upon the semi-revolution of the screw, the projecting sideof the head of the same being made to pass into the segmental recesses b b, made inthe opposite edges of the cutter-holders, as shown in Fig.' 4.

To the upward extension'of the frame A, which branches laterally in opposite directions, are secured the sliding heads E E', to which an up-and-down movementis imparted by means of the shaft F, at the opposite ends of which are formed wristfpins c, each held in a horizontally-sliding box, d, which moves back and forth within the slotopening e when imparting an up-anddown movement to the slidingheads, as shown in Figs. 5 and 6; and

the shaft F is driven` fromthe `shaft F by means of the bevel-gears G G2.

To the under side of the outwardly-projecting lip f of the sliding head is secured'the holding-shoe slight adjustment relatively to the sliding head by means of the opposite gibs, g g, made in wedge form, and operated for vthe purpose of tightening groove of the sliding head,'or for adjustment therein by means of the screws h h, (shown in section in Fig. 5,) the heads of the screws being provided with an annular groeven,- adaptthe shoe within the transverse G, which is made capable of ed to receive the open slotted head j of the tapering gibs g, as shown in Fig. 6. Upon drawing back the wedge-formed gibs g g, by means of the screws h h,

the holding-shoe G may be readilyfplaced in any required position between the gibs, and thereafter, by screwing up on one of the wedge-formed gibs and unscrewing the other, the properlateral adj ust-` ment of the holding-shoe will be effected, and

the same means will serve to rmly lock the holding-shoe in its proper position relatively to the cutting-die and sliding head. At the under side ot' the holding-shoe G is formed an undercut groove, k, the forward end of which is made in cir'cular form, and adapted to receive the conically-enlarged head lof the hollow shank r of the cutting-plunger H, which is securely held within the groove 7c by means of the clampingpiece m, which is conically hollowed to fit the rear side of the head Z. The clamping-piece m is made to it'the inclined sides of the groove 7c, and is operated to clamp the shank r by means of the screw o, provided at its head with a circumferential groove, p, within which is held the notched lug q, which extends upward at the rear end of the clamping-piece, so that the forward or backward movement of the screw will be immediately imparted to the clamping-piece m.

Upon the lower end of the hollow shank ris screwed the cutting-plunger H, (shown in section in Figs. 10 and 11,) which is made in the form of a heel, as shown in Fig. l2,the plunger H being made to screw against a shoulder, s, and loosely upon the shank r, and over the plunger H, is placed the holder I, made to t the cylindrical exterior of the shank r, and also the sides of the plunger H, as shown in Fig. 12, and between the holder l and the lower face of the holding-shoe G is placed the spiral spring J, which operates to press the inwardly-directed flange of the holder I against the upper side of the plunger H, as shown in Fig. l0. The shank r is bored out to receive the sliding paste tube and forcer K, to the lower end ot' which is secured the valve-holder L.

The valve u, which rests upon the conical valve-seat t, is provided with aguiding-stem, o, upon which is placed the downwardly-acting spring w, and at thelower side of the valve a is placed the projecting pin or stud x, by means of which the valve will be raised from its seat, so as to allow the proper quantity of paste to flow onto the upper surface of the leather blank when the same is under the action of the cutting or forcing plunger.

The valveholder L is provided with a liange,

y, which is adapted to rest against the shoulder z at the lower end of the hollow cylindrical shank r, the iiange y, which is also provided at its lower side with the clearingrecesses a5, being held against the shoulder z by means of the spiral spring a', which encircles the tube K above the shoe G, and is held between the shoe and the collar b', above which the tube K is deiiected fora short distance, and connected with one of the outlet-pipes c of the paste-cup M by means of a flexible tube, d', which is shown broken away in the drawings. Ilhe tube K at the initial point of deflection is pro vided with a lug, c', made with a hollow recess, f, at its upper surface, into which the rounded end g of the lever Nis made to rest. The lever N is pivoted to the sliding heads E and E at the point h', and from the outer short arm of the lever N connection is made to the parallel lever O by means of the link il. The lever O is pivoted to the sliding head at the point j, and at the point k on the lever 0 a pivoted connection is made to the spring-box P, within which is placed the bolt Z, provided with a head, m, between which and the closed upper end of thc box P is placed the spiral spr-ing a/,which is to bermade more rigid than the spring c,which encircles the tube K. The bolt Z'is provided with a screw-thread, o', upon which is placed the sleeve-nut p', having a milled head, q', and the sleeve-nut p is made to loosely fit the bore of the projecting lug r', which extends outward from theupper end of the frame A.

Below the table B, in the vertical plane of the cutting mechanism, are placed the intermittently-revolving carrierwheels QQ, which in this instance are arranged to revolve in opposite directions, the adjacent peripheries of the wheels being made to nearly touch each other, and also being provided with the interlocking gears s s2, by means of which an equal simultaneous movement will be imparted to the carriers, the adjacent pcripheries ot the carriers passing within the vertical slot-opening a," in the frame A. The carrier-wheel Q is secured to the frontend of a hollow sleeve, R, loosely held in the journal-box S', the proj ecting rear end of the sleeve being provided with t'our clutch-spurs, c2, which are adapted to engage with the sliding clutch d2, arranged upon the shaft T, which passes through the bore of the sleeve R, and the carrier-wheel Q is placed loosely upon the fixed stud t', which is iirmly held in the stand u', secured to the side ot' the frame A at the front edge of the slot x', (shown in Fig. 2,) and to either the stand u or the stud t is firmly secured the Xed cam @C The rim m2 of the carrier-wheel Q is provided with four circular axially-directed openings, U, one of which is clearly shown in Fig. 2, and at the edges of the same are' secured the inwardlyprojecting guiding-plates n, made of sheet-steel, and provided with the inwardly-projecting lip n3, as shown in Fig. the deposited heelblanks, the back portion `of the sheet-steel guidingplates being provided with the attached cylindrical holdingpieces n, which enter the holes vo2 made in the rim of the wheel Q at a slight distance from the edge ofthe circular opening, as shown enlarged in Fig. 13, a narrow slit, 192, adapted to receive the thin guiding-plate n2, being made from the holes 02 to the openings U, the edges a5 being made to closely embrace the edges of the heel-blanks, as shown by the dotted lines.

S, which is provided with a vertical slot a, within vwhich is placed the sliding box b2, adapted to receive the wrist-pin c3 of the operating-crank at the forward end of the shaft T, which extends through the bore of the sleeve R to a point within the hollow of the carrierwheel Q. The sliding head S is provided with a projecing shank, e2, upon lthe extension of which is cut the screw-thread f 2 and the shank e2 is bored out to receive the shaft g2, at the forward end of which is secured the cam-wheel h2, provided at itsface with three or more inclined spurs, jz. The plunger-head V is provided with a recess, Q2, adapted to receive the cam-wheel h2, and is adj ustably secured to the shank e2 by means of the double-threaded sleeve r2 and check-nut S5, the screwthread at the inner portion of the sleeve r2 being made to fit the right-hand screw-thread upon the exterior of the shank e2, and the screw-thread upon the outer portion of the sleeve being made the reverse of the thread upon the inner portion thereof, so as to iit the left-hand thread made within the cavity of the plunger-head V, vso that by turning the sleeve r2 the plunger-head V may be either projected forward or retracted, as desired. Within the cavity of the plunger-head, and at the back of the camwheel h2, is placed the ring t, which serves to support the cam-wheel when the cams .i2 are acting against the heads w2 of the clearing pins v, which are retracted by means of spiral springs u2, which encircle the clearing-pins. The small forward endsof the clearing-pins are made to project from the orifices mi m2 m2, made in the faceof the plunger-head, and the face and edge of the plunger-head V are provided with narrow grooves y2, adapted to re ceive the sheet-steel guiding-pieces n2 of the carrier-wheel Q.

Upon the rear end of the shaft g2, and within the slot z2, made in the sliding-head S,` is placed the outwardly-projecting finger a3, and to the face of the sliding box b2 is secured the arm b3, which, upon the downward movement of the sliding box by the action of the wristpin c3, will cause an angular movement of the finger a3 and the cam-wheel h2, thus causing the outward projection of the clearing-pins e, and as the sliding box b2 continues downward the finger a3 will be carried behind the downwardly-extended end ofthe arm b3, which thus serves to limit the angular movementim parted to the cam-wheel h2. The back side of the hub of thenger-piece a3 is flattened, as shown by the dotted lines in Figs. 14 and 15, and to the back side of thesliding head S is attached the spring x3, provided with an elongated face,- ys, adapted to press against the fiat surface z3, formed at the back of the iinger-piece, and thus serving to hold the cam-wheel h2 normally in the position relatively to the clearing-pins o, (shown in Fig. 4,) which shows the arm b3 at the time of its initial action upon the projecting end of the nger a3 for imparting the desired angular movement to the cam-wheel h2. A sectional view of the sliding head, showing the position of the finger-piece a3 and its accessories at the time of the initial movement l ward movement of the sliding box to the mei dium position (shown in Fig. 15) the nger a3 will have become released from the action of the arm b3, and the cam-wheel 71,2 will have been brought, by means of the action of the spring w3, back to its normal position, as shown in Fig. 4. The supporting-ring t2 is firmly held in position within the cavity of the'plungerhead by means of the screw d3. The carrierwheel Q is provided with the four chambers U', bored out at their rear to receive the Shanks e3 of the clearers f3, which are formed of the cross-bars g3 g3, let into the forward end `of the shanks e3, and at the back of the cross-bars are placed the cylindrical blocks h3, provided with cross-grooves i3, adapted to receive the cross-bars g3, so that when fully within the grooves 3 the forward edge of the cross-bars may lie in the plane of the front surface of the blocks h3. At the rear end of the Shanks e3 are placed the collars js, and between the col` lars j* and the shoulder 7c3 are placed the spiral springs Z3, which serve to hold the rear ends of the shanks e3 against the periphery of the fixed cam 'v'. The carrier-wheel Q is also provided with sheet-steel guidingplates n2, as in the case of the carrier-wheel Q, hereinbefore described; but the guiding-pieces n2 are in this case made without the projecting lip n3, and

extend to the upper face of the cylindrical blocks h3, which are to be firmly held within the chambers U by suitable means. The driv- IOO ing-pulley VW is held upon a stud at the back I of the frame A, the shaft F being driven from the pulley W by means of the gear m3, secured to the hub of the pulley, and the gear n upon the rear end of the shaft F. The loose gear o3 upon the shaft T is connected with the gear m3 upon the pulley W by means of the intermediate gear, m, and at the side of the gear o3 upon the shaft T is secured the cam p3, the resting portion qs of the cam-groove being made to extend through ninety degrees ofthe periphery of the cam, and below the shaft T and parallel therewith is placed the sliding rod r3, upon which is secured the clutch-fork s3, and between the hub of the `clutch-fork and the shoulder t3 is placed the spiral spring ua.

Upon the head o3 at the outer end of the sliding rod r3 is placed the pin w3, adapted to enter the cam-groove g3, which serves to operate the clutch d2.

loosely-revolving gear o3 is provided with the clutch-teeth x3, adapted to engage with they similar teeth of the sliding clutch gf, which is operated for engagement with the clutch-teeth :t3 by means ofthe pivoted pedal z3, which is connected to the sliding clutch ya by4 means of Q the connecting-bar at, arm b, secured to one` The outer side of theA IIO end of the rocking shaft c4, upright arm d, secured to the opposite end of the shaft c4, and the pivoted shoe e4, which enters the circumferential groove]C4 of the sliding clutch. In order that the clutch y3 maybe automatically disengaged at each complete revolution of the shaft T, I provide at the rear of the sliding clutch g3 a flange, g4, provided at its forward face with an inclined spur, h4, and to the projecting bracket i4 is secured the holding-piece J, provided at its upper end with the parallel upright guides 764, which serve to guide the under-beveled head Z* of the sliding bolt m4, which is forced downward within the holder j* by means of the spiral spring 04, which acts against the shoulder p* at the upper end of the bore of the holder and the upper end of the adjustable screw-sleeve g4 at the lower end of the bolt.

In order to prevent the untimely removal of the clutch from engagement with the catchspur of the loose gear 03, I secure a iXed pin, r4, to the attaching-base sAL of the holder jt, in such a position relatively to the iiange g4 that when the clutch is in proper engagement the iiangeg4 will revolve immediately in front of the fixed pin r4, and at the place of the automatic disengagement of the clutch I cut a notch, tt, in the edge of the flange g4 and bevel the back edge of the iiange beyond the notch t, as shown in Figs. 8 and 9. The bevel a4 serves to insure the complete closure of the vclutch upon again throwing the clutch-sleeve forward by means of the pedal z.

Upon the side of the spring-box P is secured the spring-bell Y, from the operating-lever vt of which connection is made to the arm w by means of the link x4, which is provided at its upper end with the adjustable thumb-nut g4, the arm being fixedly attached to the bolt Z.

In operating the machine the leather is to be fed under the cutting-plungers at each side of the bed B, the cutter C being made slightly larger than the cutter C, thus producing heelblanks of unequal sizes, the blanks formed by the larger cutter being adapted for the upper portion of a heel, while the smaller blanks are to`be attached thereto, so as to form the lower portion. The reciprocating movement imparted to the slides E E will first cause the holder I to be brought down upon the upper surface of the leather strip A', Fig. 10, thus clamping it firmly around the upwardly-projecting edge of the cutter; and during the continued downward movement of the sliding head the holderI will be firmly pressed against the leather at the outside of the cutter by means of the spiral spring J. The downward movement of the cutting-plungerfwhich is made' to closely fit the hollow of the cutter, will cause the separation of a heel-blank from the leather strip, and the pasting-forcer, which, after the cutting of the heel-blank, has, by reason of the multiplying action of the levers N O, a more extended downward movement than that of the cutting-plunger, will serve to carry the heel-blank A2 downward into the carrier-opening U between the adjacent edges ofthe guiding-plates n2, as shown in Fig. 11, the heel-blank iirst deposited :resting inv contact with the upper edge of the projecting lips n3, as shown in the figure, and upon the contact of the pasting-forcer with the surface of the heel-blank the valve u will be raised from its seat t, thus opening a passage for the free flow of paste or cement from the pastecup M, and upon the continued reciprocation of the sliding heads of the machine an equal number of superposed heel-blanks having a deposit of paste between them will be deposited. in the radial opening U ofthe carrier Q and in the chamber U of the carrier Q', the spring-controlled pasting-forcer K being caused to make a gradually-decreasing downward movement, by reason of the accumulated obstruction caused by the deposited heelblanks, until at a certain downward movement of the forcer the lever c* will be so acted upon by the arm u# and link x4 as to cause the bell to ring, thus notifying the operator that the proper number of heel-blanks have been cut and deposited in the carriers, upon Y which notification he ceases to feed the leather to the cutters, and by means of the pedal z3 effects the proper engagement of the clutch y3 with the clutch-spurs x3 at the side of the loosely-revolving gear o3, which engagement will cause the shaft T to make one complete revolution, the clutch y becoming automatically disengaged at the exact completion of a single revolution by reason of the contact of the inclined spur h4 of the flange gv4 against the inclined face m6 of the head Z4 of the springbolt m", which upon the initial contact Will be raised within 'its holder j* until the milled head of the adjustingsleeve g4 brings up against the lower end of the holder, thus causing the forcible disengagement of the clutch, whereupon the bolt m4 will be brought immediately back to its normal position, as shown in Fig. 2, by means of the spring o, which surrounds the bolt m4 within the holder, thus leaving the clutch ya in a position for ready re-engagement subsequent to the renewed ac-VY IIO clutch aZ"z in engagement with the clutch-spurs cl of the sleeve R, to which the carrier Q is attached, will be in operative engagement only when the forcer Kis elevated above the openings or chambersV of the carriers, thus allowing the carriers Q and Q to be moved through a space of ninety degrees, at the completion of which movement the clutch (Z2 will become disengaged by the action of the camgroove g3, the quarterrevolution of the carriers serving to bring a new opening and chamber under the cutters C C', and also to bring the opening and chamber previously filled with heel-blanks to an adjacent position preparatory to the action of the plunger V, the forward movement of which serves to force the accumulation of smaller heel-blanks in the opening U from the said opening into forcible contact with the accumulation of larger heel-blanks in the chamber U of the carrier Q', and upon the retrograde movement of the plunger V, the clearing -pins o2, which are proiected from the face of the plunger by the action of the cam-wheel h2, as hereinbefore described, will serve to prevent the accumulated compressed heelblanks from following the plunger V in its backward movement, and upon the continued action of the machine the accumulated heel-blanks in the chamber U willbe brought to the lower portion of the carrier Q and will be discharged therefrom by the action of the discharging-forcer f3 andV fixed cam o.

The opening U in the carrier Q is provided at one side with the projecting lip or spur ui", and thedirect forward movement of the plunger V and the angular movement of the carrier Q are to beso timed relatively to each other that the lip 11.5 will bring up against the moving forward end of the plunger, thus forming a stop to properly limit the forward movement of the carriers.

The machine may be readily adapted for making heels of various sizes by changing the guiding-plates n2, and correspondingly changing the cutters and cutting-plungers, and in forming low heels a single cutter at either side of the machine may be used, the accumulated cemented heel-blanks being discharged from the chamber of the carrier, as before. It will also be readily seen that the relative movement of the carrier Q may be reversed; but the operative arrangement of the carriers as shown and described is preferred, and various devices may be employed to impart an increased variable movement to the forcer, which serves to carry the heel-blanks through the hollow of the cutter and into the receiving-carriers.

The screw-sleeve p upon the bolt Z', which moves up and down with the sliding head, is to be so adjusted relatively to the movement of the cutting-plunger that immediately upon the separation of the heel-blank A2 from the leather strip A', by the conjoint action of the cutter C and cutting-plunger H, the milled head q shall bring up against the upper surface of the projecting lug r', and upon the continued downward movement of the sliding head the outer end ofthe lever O will be caused to rise relatively to the sliding head, and this upward movement will be imparted to the lever N by means of the link i', thus causing an increased downward movement at the end g of the lever N, and the increased downward movement `of the end g of the lever, which rests upon the projecting lug e', will cause the desired increased movement of the forcer K in opposition to the upward action of the comparatively-weak spring a', so that while the cutting-plunger will have been moving downward to the position relatively to the j cutter C shown in Fig. l1, the forcer K will 7o have been carried downward to the position within the opening U of the carrier-wheel, shown in the same figure, the forcer being operated in this case without causing the compression of the comparatively stiff spring n in the box P; but upon the subsequent reciprocation of the sliding head, and the resulting formation of an additional heel-blank, the forcer K will be allowed to have a restricted `downward movement by reason of the result- 8o lng compression of the spring n, which compression will be correspondingly increased at each reciprocation of thesliding head until y a sufficient number of heel-blanks have been deposited upon the guiding-plates in the open- -ing U of the carrier-wheel Q.
